Perimeter of a Trapezoid
The perimeter of a trapezoid can be described as the distance around all four sides of the trapezoid. The green box around the rectangle below indicates the perimeter of the trapezoid.
The perimeter of a trapezoid can be calculated by adding the lengths of all the sides together. So if we are given a trapezoid with sides 12, 14, 10 and 8, the perimeter would be .
